Global society faces various issues, including addressing natural disasters, responding to burgeoning healthcare
and medical needs, enhancing information security and ensuring human security.
Here, we spotlight how we are helping establish a society where people can lead safer and more secure lives.
Examples include an inter-public facilities hotline system and an ICT system for World Cup stadiums.

Ensuring an Information Exchange Network in Disaster-hit Regions
with a Robust Inter-public Facilities Hotline System
The Great East Japan Earthquake damaged the public
network in Rikuzentakata City, Iwate Prefecture, causing
communication difficulties stemming from cable severances
and extreme line overloads. This greatly affected
communications between elementary and junior high schools
and other public facilities that served as shelters.
After disasters and other emergencies occur, fax-based
communications become vital for evacuee rosters, and
sharing handwritten maps and messages, and providing
visual information that is difficult to convey orally.
NEC delivered a robust disaster hotline system for
communications between Rikuzentakata City’s elementary
and junior high schools and other public facilities. The system
combines an IP announcement broadcasting system with the
existing public network. This setup has established proper
phone and fax communication between local public facilities
even if a disaster occurs.
So that school staff can use it without confusion during
emergencies, the system functions as a regular contact
network between elementary and junior high schools.
Municipalities around Japan have drawn from the
experience of the Great East Japan Earthquake in reinforcing
and rebuilding means of conveying and sharing information
that is vital in disasters. Schools and other public facilities
not only secure the safety of students and staff but also
function as disaster centers and shelters for residents,
making it essential to maintain more robust information and
communications infrastructures.
NEC will take advantage of its
advanced wireless technologies,
disaster information systems, and
other know-how to promote the use
of this system going forward. NEC
will also propose the system to
hospitals, nursing care facilities, and
community centers, as well as to
elementary and junior high schools
around Japan that serve as disaster
refuges, thereby contributing to
community safety and security.
